* Use generics in more places. * Use `ref` in more places. * Use `for` in more places. * Use a little bit of C++ interop. * Use an adapter for the `char`-or-EOF result of reading a char instead of pure `i32`, and use char literals where possible. --------- Co-authored-by: josh11b <15258583+josh11b@users.noreply.github.com>
